Will Anthropic’s valuation hit … by December 31?

Platform comparison

Market context

Anthropic’s private-market valuation must reach the listed threshold by 31 December 2026, measured solely by the Nasdaq Private Market (NPM) Price, to resolve this contract as “Yes”. The current crowd-implied probability sits at 12% YES, a stark divergence from Polymarket’s 99% line on a $1T milestone and 95% on $1.1T, while analyst consensus via Moonberg pegs the July 2026 valuation at $1.14T—18% above its Series H-1 round.

Historical precedents for secondary-market valuation spikes in pre-IPO tech firms show that NPM prints often lag headline financing announcements, creating temporary dislocations between prediction-market odds and actual valuations. Polymarket’s base-rate market on Anthropic beating OpenAI’s NPM valuation by June 30 2026 settled at 83% YES, reflecting a sustained secondary-market surge that pushed Anthropic to $936B against OpenAI’s $822B by May 2026, yet the current 12% line suggests traders doubt a further 65% jump to $1.9T within six months.

Traders should monitor daily NPM updates at 1:00 PM ET, particularly any post-financing re-pricing following Anthropic’s recent $965B round, and watch for IPO-timing signals from Nasdaq or SEC filings that could accelerate secondary liquidity. A CNBC report from May 2026 noted Polymarket’s launch of private-company valuation contracts specifically for Anthropic and OpenAI, highlighting how oracle-driven markets now track gated NPM prints rather than press releases, making the next quarterly NPM update the critical catalyst for this contract’s resolution.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi vs Polymarket trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
